Patent EP-0194076-A2 (EP)
Inventor: HICKS RICHARD BANFIELD
IPC: F16K24/00
Filed: 1986-02-20
Abstract: A valve (10) is provided primarily for medical or surgical aspiration equipment, in which body fluid (e.g. from a wound or breast) is drawn into a collecting bottle by the removal of air through a pipe(11), the pipe (12) of the valve being connected, possibly via a filter, to the low pressure side of an air pump. 
     An elongated, hollow valve member (14) closed at its top end (16) and open at its bottom end (27) has limited reciprocative movement coaxially within a chamber (13) between the valve-open position, in which it is shown, and a valve-closed position in which a sealing ring (32) at the closed end (16) of the valve member (14) makes contact with a valve seat (31) surrounding the outlet opening (17) of the chamber (13). 
     By the co-operation of fins (18, 19, 20) on the valve member (14) with the inner periphery of the chamber (13) and with a protrusion (22) thereof the valve member (14) is held in an angular position such that the opening (23) of the pipe (11) in the chamber wall and an opening (24) provided in a shoulder (25) of the valve member are in register when the valve is open. Thus indrawn air passes to the interior of the valve member (14), thence into the chamber (13) through slits (28) defined between the open end (27) of the valve member (14) and the bottom (15) and the bottom (15) of the chamber, thence upward through the annular passage between the valve member (14) and the inner periphery of the chamber (13) and so out of the chamber (13) through the outlet (17). 
     If the slits (28) are occluded e.g. by froth or liquid drawn in from the bottle through the pipe (11) the resulting pressure drop across the valve member (14) will raise it to the valve-closed position.

Abstract: An improved method of severing a large area of an amorphous semiconductor device material into smaller area devices. The material includes an amorphous semiconductor body disposed between an electrically conductive substrate and a transparent electrically conducting coating. The transparent coating is brittle and upon severing can leave electrical conducting shards that short circuit the substrate to the coating. This problem is overcome by supporting the coating, either bare or with a protective member, which may be resilient, and applying a shearing force to the substrate. Cardboard, paper and polymers may be used as protective members.

Abstract: A flat visual display device (46) is disclosed herein and includes a flat face plate (12) having a front face (14) and an opposite back face (16) and electrically positive means on the latter which, as a result of the impingement of the electrons thereon, provides a visual image through the front face (14) of the face plate (12). The device utilizes an arrangement including cathode means (26) for establishing a uniformly dense space-charge cloud of free electrons (54) within a planar band parallel with and rearward of the back face (16) of the display face plate (12). Means including an apertured address plate (26) disposed in spaced-apart, confronting relationship with the back face (16) of the face plate (12) between the latter and the uniform space-charge cloud (54) acts on the electrons within the cloud in a controlled way so as to cause the electrons acted upon to impinge on specific areas of the electrically posi­tive back face plate (16) means of the display face plate (12) in order to produce a desired image through the face plate's front face (14).

Abstract: Wideband amplifier having a differential amplifier or single-ended amplifier and having a capacitance compensation circuit is disclosed. The amplifier detects the voltage variations of a signal input node (90,91) or a signal output node (92,93), generates a compensation current equal in magnitude and opposite in direction to a current flowing in a parasitic capacitance such as a transistor junction capacitance, and cancels the parasitic capacitance associated with a node by supplying the compensation current in a reverse phase to the node to which the parasitic capacitance is attached. As a result, a wideband amplifier is achieved, and it can also be used as a high-speed comparator. Further, harmonic distortions causing from the voltage dependency of the parasitic capacitance can be reduced by flowing the compensation current corresponding to a voltage impressed to the junction capacitance.

Abstract: A hinged sliding door for passenger-conveying vehicles, in particular rail vehicles, whose door leaf (1) can be slid in its longitudinal direction on a guide element (3), the guide element being swivellable transversely to the plane of the door leaf by means of cranks (4, 5) with vertical crankshafts (8, 9). The cranks (4, 5) form, together with this guide element (3) and the door frame (17), a four-bar linkage with opposing cranks. As a result, it is achieved that the door leaf (1) assumes a highly inclined position when the guide element (3) swivels, by means of which position the leading edge of the door leaf is lifted out of the door opening. The cranks (4, 5) are expediently of the same length. In order to coordinate the sliding and swivel movement, the door leaf is guided at its upper and lower end by guide rails (10).
